W. Va. Code § 31-15-13
Any bonds or notes issued by the authority or any other public body or authority of the state pursuant to the provisions of this article or any other provision of this code and at any time outstanding may at any time and from time to time be refunded by the authority by the issuance of its refunding bonds or notes in such amount as it may deem necessary to refund the principal of the bonds or notes so to be refunded, together with any unpaid interest thereon; to provide additional funds for the purposes of the authority; and to pay any premiums and commissions necessary to be paid in connection therewith. Any such refunding may be effected whether the bonds or notes to be refunded shall have then matured or shall thereafter mature, either by sale of the refunding bonds or notes and the application of the proceeds thereof for the redemption of the bonds or notes to be refunded thereby or by exchange of the refunding bonds or notes for the bonds or notes to be refunded thereby. Such refunding bonds or notes shall be issued in conformance with the provisions of sections nine and ten of this article.
